Vic woman sexually assaulted in front yard

The same man is believed to be responsible for the sexual assault of a woman in her front yard and the attempted abduction of a teenage girl in a Victorian town.

A 55-year-old woman was gardening in the front yard of a Wodonga house when she was approached by a man and sexually assaulted on the evening of March 25.

Then on March 31, the same man is believed to have made a brazen attempt to abduct a 16-year-old girl, also in Lawrence Street.

The girl went to the man's aid after he pretended to fall over and he then dragged her into a black sedan and hit her with a blunt object before she managed to escape, police say.

Police describe the man as Caucasian, with a medium build, aged 55 to 60 with grey hair and a pot belly.

Several cars slowed down as they drove past the scene during the initial assault and police are calling for anyone who may have seen something, thinking it looked like a domestic dispute, to come forward.

Detective Leading Senior Constable Carl Keenan, of the sexual crime squad, said police needed the public's help to catch the brazen offender.
